Influences of thermal aging on properties and pyrolysis products of tire tread compound

The study of ultrasound-assisted oxidative desulfurization process applied to the utilization of pyrolysis oil from waste tires

“…Jitkarnka found many carbon blacks in the pyrolysis oil samples from waste tires (Jitkarnka et al, 2007). Table 1 shows that the specific gravities and elemental contents of carbon, sulfur and nitrogen in pyrolysis oils were higher than those obtained for commercial diesel fuels (Laresgoiti et al, 2004), resulting in high sulfur oxide emissions and sulfate particulate matter (PM) production when heating pyrolysis oil directly.…”

An economic analysis of the continuous ultrasound-assisted oxidative desulfurization process applied to oil recovered from waste tires

“…Jitkarnka et al (2007) indicated that a large amount of black carbon and a range of chemical compounds were present in pyrolysis oil (Table 2) (Ucar et al, 2005). The specific gravity and amount of sulfur are higher in Shih Chang pyrolysis oil than in commercial diesel fuel, which could cause serious environmental pollution, such as high SO 2 emission and sulfate PM.…”

Waste Tyre Management in Gauteng, South Africa: Government, Industry and Community Perceptions

“…Old tyres are usually retreaded, reclaimed, devulcanised to rubber for re-use or further processed [8]. In South Africa, the Recycling and Economic Development Initiative of South Africa (REDISA) plan, Fig.…”
